What energy efficiency ratings mean and why they’re important01/10/2017The cost to heat and cool your home makes up more than half of your utility bills. That’s why it’s imperative to look for a system that provides quality comfort in your Rocky Mount home while still ensuring energy efficient. Better energy efficiency means your system is operating well while using less energy. Whether you are looking into a replacement air conditioner or furnace or considering to upgrade your existing equipment to be more energy efficient, there are some ratings to know that will help you during the procedure. So what exactly do those energy efficiency ratings mean? SEER (used to measure cooling efficiency) SEER stands for Seasonal Energy Efficiency Ratio. The SEER rating reflects the effectiveness of your unit at different temperatures, in other words, seasonally in Rocky Mount. A greater SEER rating denotes a greater energy efficiency, which will turn into lower utility bills. The Department of Energy expects a minimum 13 SEER-rating for cooler states in the north and a 14 SEER-rating minimum for humid, southern states. If your home has an aged unit with a lower SEER-rating, you could see radical energy savings after an upgrade. AFUE or HSPF (used to measure heating efficiency: gas or electric) AFUE stands for Annualized Fuel Utilization Efficiency ratio and it keeps track of the percentage of heat created for every dollar of fuel consumed. You can consider it as the MPG on your car. The higher the AFUE-rating, the less your energy costs. If your furnace has a AFUE rating of 80, that denotes that 80% of the heat generated is exhausted to heat the home, while 20% of the heat is wasted through venting. HSPF stands for the Heating Seasonal Performance Factor and is used to measure the heating efficiency of heat pumps. It is the SEER rating for winter as it only measures your unit’s heating productivity. Again, the larger the number, the more energy efficient the heat pump.
